In the preferred construction of the invention, I provide the garage Ihaving the doors 2 and 3 for the purpose of closing the doorway 4.

As shown in Figs. 2 and 3 each door has fixed to its upper edge 5 theU-shape bracket 6 having the bolts 1 received through holes therein andthrough the upper edge of the door.

Integrally connected with the bracket '6 is the vertical pin 8 whoseupper end is rotatably mounted in the annular ball bearing 9 suitablyfixed in the recess H3 in the plate I I which extends from the side wallI2 to the side wall I3 of the garage.

The top of the bracket Bis spaced from the plate ll whereby the door maybe elevated from the position shown in Figs. 2 and 3, for purposeshereinafter fully explained.

As shown in Figs. 2 and 4, fixed to the outer bottom edge [4 of eachdoor is the U-shape bracket l5 having the bolts 16 received throughholes therein, and the bolts also are received through the bottom of thedoor.

Suitably fixed to the bottom of the bracket [5 is the cam I! having inits lower side I8 the curved grooves I9 and the curved obtrusions 2D.Formed integrally with the lower side I8 of the cam H, and centrallydisposed thereof, is the downwardly extending vertical pin 21 having itslower end rotatably mounted in the bearings 22 and 23 received in thehole 24 in the housing 25 which is fixed, as by the bolts 26, to theside frame 2? of the garage l.

Slidably mounted in the bearing or holes 28 and 2% in the housing 25 arethe vertical push rods so and at having the forks 32 and 33 formed intheir upper ends in which are rotatably mounted the ball rollers 35 and35 each being positioned in alignment with the outer edge of the caml'i, whereby when the rods 30 and ti, as hereinafter explained, moveupwardly the rollers contact the lower side of the cam.

In the ground 3% is the cavity 3'! which extends from the point 38 infront of the garage to the rear wall 39 of the garage and from the sidewall ii to the side wall l3.

The frame ll], comprising the front and rear walls 4! and 42 and theside walls Q3 and M, is positioned in the cavity 31. Spaced from therear wall i2 is the horizontal partition 15 which extends from the sidewall @3 to the side wall 44. Extending from the partition 45 to thefront 'wall ll are the parallel and spaced apart supports 46 and tispaced equi-distant from the side walls 43 and 4t.

Pivotally mounted in the supports 46 and ll, and centrally disposed ofthe cavity 31, is the rocker frame 43 which comprises the shaft 49having its ends 5G and El pivotally mounted in the supports it and H.The spaced apart and parallel plates 52 and 53, integrally formed withthe ends of the shaft 49, extend at right angles thereto, and the endplates 5% and 55 are suitably fixed to the ends of the plates 52 and 53.

Spaced from the front wall ll and extending parallel thereto, is thehorizontal bar 53 whose downward movement is limited by the spaced apartblocks 5? fixed to the front wall M and extending inwardly thereof.

Fixed to the floor 58 of the cavity 31 is'the bracket 59 having thespaced apart upwardly extending arms 6% and ti having holes therein inwhich is received the pin 62 on which the lever 63 is pivoted. On thefront end of the lever 63 is the weight 64, which is slidable on thelever and which may be fixed in a predetermined position on the lever asby the set bolt 65. In the. rear end of the lever 63 is the notch. E6into which is received the plate 55. The weight 84 is manually adjustedon the lever 63 so that the rocker frame 48 shall be retained inhorizontal position when the various mechanism herein previously andafter explained are in inoperative positions.

Fixed to each end of the bar 56, as by the pin 66, is the front end ofthe horizontal lever 67 which is pivoted to the spaced apart arms 68 and69 fixed to the floor 58. Pivoted, as by the pin Hi, to the rear end llof the lever 6'! is the upper end of the vertical rod 72 having itslower end pivoted to the horizontal lever 13 which is pivoted on the pinM which is rotatably received in a hole in the vertical arm 75 fixed tothe fioor 58.

Formed in the inner end of the lever E3 is the notch 16 which receivesthe front end of the plate 52, whereby downward movement of the barcauses the rear end of the lever 13 to move downwardly thereby causingthe front end of the frame to move downwardly to the position shown inFig. 12.

The lever 11 is pivotally mounted on the pin 18 which is received in theupwardly extending bracket '19 fixed as by the bolts 35!, to the floor58. The lever has the notch 8! in its inner end 82 and the notchreceives the rear end of the plate 52 whereby, when the front end of theframe as moves downwardly, the outer end of the lever 71 moves upwardly.

Fixed to the outer end of the lever Tl is the Vertical rod 83 havingfixed to its upper end the spring catch 84 having the yieldable jaws 35.The outer edge 86 of the L-shape male member 37, fixed to the outerlower edges of the doors 2 and 3, is adapted to be received between thejaws, when the doors 2 and 5 are open, to retain the doors in openposition.

The rod 8 3 is slidable beneath the plate 83' fixed to the side wall 43.

Fixed to the catch 84 is the arm 88 which is pivoted to the vertical arm89 which is fixed to the top of the side wall 33. The other end of thelever 88 is pivoted to the arm 96 which extends downwardly from thetrough 9!. Fixed to the bottom of the trough 9! is the projection'QZpivoted to the vertical arm 93 fixed to the top of the side wall 43.

In the trough Si is the roller a having the integrally formed eye-bolt95 extending outwardly through the slot 96 in the trough. Fixed in theeye of the eye-bolt $5 is the end of the connecter 9's having its otherend connected with the roller or slide as slidable on the horizontal rod99 fixed to the lower edge of the doors 2 and 3.

Pivoted to the lower end of the rod 39 is the horizontal lever Hi6 whichis pivoted on the pin ml which is received in the upper end of thevertical arm 32 which is fixed, as by the bolts [03, to the floor 58.Pivoted to the outer end of the lever it is the lower end of thevertical rod Hi4 having its upper end pivoted to the inner end of thelever H35 pivotally mounted on the pin lilfi received in the upper endof the vertical arm Hill which is fixed, as by the bolts l 83, to thefloor 58. The outer end of the lever m5 has the notch H16 therein inwhich is received the rear end of the plate 52, whereby when the bar 56is depressed and the rear end of the frame as moves to the upwardposition shown in Fig. 12 the outer end of the lever R35 is caused tomove upwardly from the position shown in Figs. 9 and 13 to the positionshown in Figs. 10 and is thereby forcing l the rod 30 upwardly andcausing the roller 34 to engage the obtrusion 20 on the lower surface ofthe cam which raises the door so that the space, shown in Figs. 2 and 3,between the bracket 6 and the plate H is eliminated and the bracket 6contacts the plate i l. Upward force. of the roller Ed on the obtrusion26 causes the cam to roll on the roller from the position shown in Fig.9 to the position shown in Fig. 10 thereby causing the doors 2 and 3 tomove from the closed positions shown in Fig. 5 to the open positionsshown in Fig. 7.

Spaced from the rear wall 42 is the bar 509 having pivoted to its endsthe rear ends of the levers lit Whose rear ends ill extend at an angleto the main bodies N2 of the levers and each have the notch H3 thereinwhich receives the bar M19. The body H2 is pivoted on the pin H3 whichis received in the upper end of the arm H4 fixed to the floor 58 of thecavity. The front end N5 of the lever HG has the notch H6 therein inwhich is received the rear end of the plate 52., During the period whenthe bar M59 is in the depressed position shown in Fig. 12, or at periodswhen the bar we is manually depressed the rear end of the frame 48 iselevated thereby causing the mechanism in Figs. 9 and 13 to assume thepositions shown in Fig. 10 and Fig. 14 whereby the front end of thelever Hi9 forces the rod 3!) upwardly causing the roller 34 to engagethe obtrusions on the lower surface of the cam I1 thereby rotating thecams I1 and opening-the doors of the garage.

In the space H6, which is betweenthe rear wall 42 and the partitionorsupport 45, is the vertical bracket II1 fixed to the'fioor 58. Thebracket II1 has the pin H8 in its upper end on which is pivotallymounted the lever:I I9 having the notch I20 in its front end and inwhich is received the horizontal leg I 21 of the L-shape member I22having its vertical leg I23 fixed to the rear surface of the bent barI24 having its ends bent to form loops I25 and having its body portionslidably mounted between the vertical legs I26 of the L-shape membersl2-1 fixed to the floor 58.

Fixed to the rear end of the lever H9 is the upper end of the rod I28having its lower end pivoted to the rearend of the bar I29 which istwisted at I30 so that its front end I3I shall be horizontal. The frontend has the hole I32 therein in which is received the vertical post I33which is fixed, as shown in Figs. 5, 15 and 16, to the rear ends of thehorizontal rods I34 which extend forwardly and outwardly of the cavity31. The bar I29 extends from the space II6 through the aperture I35 inthe partition '45 whereby downward movement of the bar I24 causesdownward movement of the front end of the lever H9 and through the rodI28 the bar I29 is moved forwardly and outwardly. Each rod slides on thesupport I36 and between the spaced apart pins I31 fixed in the floor.Fixed to the top of the post I33 is the coiled spring I38 which is fixedto the front side of the partition 45, whereby when no downward pressureis being exerted on the bar I24 the spring I38 urges the rods I34, barI29, and other mechanism shown in Figs. 15 and 16, to the positionsshown in Fig. 15.

When the front and rear wheels I39 and I40, or both of the automobileI4I roll onto the runways I42 the bar 56 first is forced downwardlywhich, through mechanism previously explained partly comprising thelevers 61, and 13, frame 48, levers I05 and I00, and rod 30, causes theroller 34 to engage the obtrusion 20, closing the spaces between thebrackets 6 and the plate I I, and the position shown in Figs. 2 and 9,and the cam is caused to rotate thereby causing the doors 2 and 3 topartly open to the position shown in Fig. 10 and to the full position.After the wheels I39 and I40 have passed to the rear of the runways I42the doors 2 and 3 drop by gravitation and the obtrusions 20 contact therollers 35 of the push rods 3I and the doors 2 and 3 are caused to movefrom open position to closed position since, when the rollers 35 arecontacted by the obtrusions 20 the weight of the doors causes the doorsto move to permit the rollers 35 to be positioned in contact with thegrooves I9, as shown in Fig. 9.

Connected with the front ends of the rods I34 are the upwardlyprojecting ears I44 having pivoted thereto, as by the pins I45, thevertical posts 146. Each spring I41, having its ends fixed to the earI44 and the post I46, urge the post to the vertical position shown inFigs. 15 and 16.

When the automobile I44 has passed inwardly of the garage I and from therunways I42 and I43 onto the board I48, which rests upon the bar I24,downward pressure is exerted on the bar I24 and the rods I34 are forcedoutwardly and forwardly. The vertical posts I46, connected with theirfront ends, are forced beneath the inner ends of the horizontal rodsI00, and when the roller 34, levers I00 and I05 and rod 30 are in theposition shown in Fig. 13, at which time the locked against the doors 2and 3 being opened by downward pressure being exerted on the runways I42and I43.

When for any reason the mechanism is positioned as shown in Figs. 10 and14, and the posts I46 cannot'be inserted or moved beneath the leversI09, downward pressure on the board I48 or bar I24 causes the rods I34to move forward and the top of the posts I46 contact the levers I00 andthe posts I46 move to the position shown in Fig. 17.

As previously mentioned when the doors 2 and 3 are closed and downwardpressure is exerted on the runways I42 and I43 which, through mechanismpreviously explained, causes the rollers 34 to engage the obtrusions 20on the cams and simultaneously the outer end of the lever 11 movesupwardly thereby through the arm 83 and lever 88 the trough 9I assumesthe position shown in Fig. 21 whereby the roller 94 rolls in the troughand the slide 98 slides on the rod 99. The connecter 91 prevents asudden gust of wind from closing the doors 2 and 3 or stopping thecontinuous opening movement of the doors, caused by the rollers 34contacting the cams I1, because the connecters 91 prevent closingmovement of the doors.

When the doors 2 and 3 are in closed position, the automobile MI is inthe garage and it is desired to drive the automobile from the garage,the operator backs the automobile until the front wheels I39 are removedfrom the board I43 whereby, through urging of the spring I34, the postsI46 are removed from beneath the levers I00 and weight of the rearwheels I46 forces the bar I09 downwardly thereby operating mechanismpreviously described which assumes the positions shown in Figs. 10 and14 whereby the doors 2 and 3 are automatically opened.

The invention may be utilized to automatically open and close doors,gates and the like.

While I believe that the form of the invention illustrated in thedrawings and referred to in the above description, as the preferredembodiment, is efficient and practicable, yet realizing that theconditions concurrent with the adoption of the device will necessarilyvary, I desire to emphasize the fact that changes in the details may beresorted to, when required, without sacrificing any of the advantages ofthe invention as defined in the claims. Hence I do not limit myself tothe precise details of the materials or the size and shape thereof asset forth, but consider myself at liberty to make such changes andalterations as fairly fall within the spirit and scope of the appendedand final claims.

What I claim as new and desire to secure by Letters Patent is:

1. A garage having a platform extending from within said garage to apoint in front of its front wall and having a pair of doors mounted onits front wall, said platform adapted to support an automobile, each ofsaid doors being pivotally mounted at its top and bottom, a rotatablecam operatively connected with the lower pivot of each of said doors,and rotation of said cam in one direction being adapted to effectmovement of said door and open said door, the front end of said platformbeing adapted to move downwardly when the front Wheels of saidautomobile are thereon, means operative by the downward movement of thefront end of said platform to cause rotation of said cams to effectopening of said doors before said automobile reaches said garage, andmeans operative by the weight of said automobile, and which preventsoperation of said means operative by the downward movement of the frontend of said platform, whereby said doors cannot be opened by downwardmovement of the front end of said platform and auxiliary means to assistopem'ng of said doors when said front end of said platform is forceddownwardly before said automobile reaches said garage.
